A Canadian family found 102 snakes in its home last weekend when the reptiles attempted to hibernate for the winter.

CBC News reports that the Regina, Saskatchewan, family initially came upon just a few of the harmless garter snakes in the basement and then uncovered many more wriggling around in crevasses in the kitchen and bedrooms.

They called the Salthaven West Wildlife Rehabilitation and Education Center, which sent two people over to catch the reptiles.

Megan Lawrence, director of the shelter, said,

"They were starting to end up everywhere in the house but in the basement. For the most part they were in tight spaces. Cracks in the floors, cracks in the walls, between boxes, underneath things — anywhere they could get into basically."

The snakes weren’t moving very fast or trying to hide, she added, because they had already begun to hibernate.

Lawrence and her colleague put the snakes in pillowcases and buckets before separating them by size.

The largest snake was almost a meter in length and the shortest about 9 inches.

Ray Poulin of The Royal Saskatchewan Museum says it’s common for snakes to seek shelter from the cold in large groups inside homes.
